2018 GMC C6: VIN configurations and specifications
Multiple VIN patterns can share the same trim. Compare their recorded equipment, then open a specification page for the full details.
Where these specifications come from
Specifications combine decoded VIN data, including NHTSA vPIC , with inventory records. If decoding does not identify a trim, a recorded inventory trim may be shown. VIN patterns do not confirm every installed option.
Counts describe observed VINs in our database, not factory production totals. Prices are median asking prices from qualifying U.S. listings, not original MSRP. Check the vehicle’s build sheet for exact equipment.

Frequently asked questions
Why do 2018 GMC C6 prices range from $13,860 to $24,962 in Ohio?
The spread comes down to configuration and mileage: higher-mileage, base-configuration examples sit near the low end, while low-mileage and premium configurations reach the top. Half of all listings fall between $17,995 and $20,855 — see the mileage and trim breakdowns above for where a specific vehicle lands.
How much should mileage change the price of a 2018 GMC C6?
Across the lowest- and highest-mileage groups, asking prices differ by roughly $1,200 per 10,000 miles. These groups contain different vehicles: this is not a same-trim adjustment or a forecast for one car. Compare the mileage and trim tables, then check condition, equipment and vehicle history.
Do GMC C6 prices in Ohio differ from the rest of the country?
Yes. The average in Ohio is $19,454, which is $2,879 below the national average of $22,333. Local supply, demand and transport costs all play a part.
How many 2018 GMC C6 are for sale in Ohio right now?
5 in total, nearly all pre-owned. Counts refresh daily from live dealer inventory.
Is this the trade-in value or private-party value of my 2018 GMC C6?
These figures describe dealer asking prices, not trade-in offers, private-party sale values or completed sale prices. Use them to compare advertised vehicles. To find out what a buyer or dealer would pay for your car, request an offer that takes its mileage, condition, equipment and history into account.
How we calculate these prices
We track 5 active listings for this vehicle across dealer sites in Ohio, updated every day. Average and median are computed from real asking prices on live listings. We exclude the top and bottom 2% of prices to reduce the influence of extreme values. This does not verify title status or guarantee that every erroneous listing is excluded. Prices reflect dealer asking prices — not final sale prices — and exclude taxes, fees, and incentives. Trim and mileage move the price more than any other factor; see the breakdowns above.
